StreetWires' high-performance Y-adapter features one female and two male RCA connectors, making it easy to combine two channels into one or split one channel into two. Like the rest of the ZeroNoise® 9 Series, an ultra-grip Teflon surround protects the oxygen-free copper center wire and twisted outer conductor. The precision-machined connector with its eight gripping surfaces provides the tightest possible connection for minimal signal loss. Package includes a pair of Y-adapters. Warranty: lifetime.
